Clarke CHT 141 Operating Instructions
MAINTENANCE
Each torque wrench has been lubricated before leaving the factory. If the torque wrench
has not been used for some time, operate it several times allowing the lubricant to re-coat
the internal working parts.
• After use, keep adjustment at lowest torque setting.
• Do not turn handle below lowest torque setting.
• Clean wrench by wiping. Never immerse in any type of cleaning fluid.
• The wrench may occasionally require servicing/recalibration in order to ensure accurate
readings, in which case, contact your CLARKE dealer
